Patients that suffer from incurable disease are more likely to be deteriorated in various areas of their lives, such as the quality of life, including physical and psychological health, social relations, and the environment. This study was designed to find out the quality of life and effects of group art therapy on the emotional expression and self-image of patients with incurable diseases. We employed the use of WHOOQOL–CS (Quality of life) and DAS as research tools to compare the emotions, quality of life, and self-image. The subjects of this study were ten adults with 10 sessions and 120 minutes for each session. Based on data, activities and works that recorded the whole process, we analyzed the quality of each session, group stage and individual. The results of this study were as follows. First, group art therapy has brought positive changes to the quality of lives of adults living with incurable diseases. Second, as a result of DAS, group art therapy brought positive changes in expressing various emotions to the patients with refractory adult patients who led daily lives while helpless, depressed and having negative self-image due to illness. Moreover, patients with refractory illness who showed changes in self - image and emotions had a meaningful change in the social relation area of quality of life by receiving care in groups, recognizing oneself positively through art medium and emotional ventilation. This study is limited to a single group. However, it is important to suggest the need for group art therapy and can have a positive impact on their lives as a social concern and psychological interventions for chronically incurable patients.
